Brushless dc motor with large air gap

Electrical Engineering in Japan, 1997
The authors propose a new brushless dc motor for pumps, with a large air gap of 8 mm, compared with the conventional gap of 1 mm. The conventional pump system is composed of an induction motor, a magnetic coupling, and a magnetic rotor with vane. This rotor receives power from the magnetic coupling.

Regulatory network rewiring drives strain‐specific lipid accumulation response in Chlorella sorokiniana under nutrient starvation

The Plant Journal, Volume 125, Issue 1, January 2026.
SUMMARY Microalgae modulate lipid metabolism in response to nutrient stress, offering a promising avenue for sustainable biofuel production. However, a mechanistic understanding of the transcriptional programs driving triacylglycerol (TAG) accumulation remains limited, particularly in non‐model species.
